  • Laying of flexible pipe
    Patent number: 4071203
    Abstract: Flexible plastic pipe is reeled onto a reel mounted on a truck and is temporarily laid on a field site by driving the truck along, permitting the flexible pipe to unreel. A brake on the reel puts tension on the flexible pipe as it is being unreeled. To retrieve the flexible pipe, it is cut into segments, each segment being of a shorter length than the total amount of flexible pipe reeled onto the reel. Then, each segment is reeled onto the reel with the truck stationary and the reel driven through a transmission from the truck.
